There is provided an elevator operation control device in which for an elevator provided with a destination floor reservation device in an elevator hall, disadvantages can be overcome reliably that a user who observes a predetermined riding rule cannot ride on the elevator because of a user who does not observe the riding rule and that the operation efficiency of elevator is lowered. For this purpose, the destination floor reservation device is provided in an elevator hall so that a user registers his/her own destination floor using the destination floor reservation device. Also, when a car stops at the elevator hall, a non-reservation user riding on the car without registering the destination floor using the destination floor reservation device is detected based on the information on the user having registered the destination floor using the destination floor reservation device and the information on the user in the car. Further, when the non-reservation user is detected, the car is inhibited from starting from the elevator hall, and the car is stopped at the elevator hall.
